This does not make sense as a chemical equation. However, it seems like you are trying to equate different forms of calcium carbonate (CaCO3), calcium oxide (CaO), calcium hydroxide (Ca(OH)2), and the original calcium carbonate (CaCO3). This is incorrect, as these compounds have different chemical compositions and properties. Can you provide more context or clarify what you are trying to ask?
